Register Definitions
RSTN: Internal timing reset control
PW: Power down control
DIF1-0: Audio data interface formats (Table 3)
For addresses from 03H to 1FH, data must not be written.
When PDN pin goes “L”, the registers are initialized to their default values.
When RSTN bit goes “0”, the only internal timing is reset and the registers are not initialized to their default
values. All data can be written to the register even if PW or RSTN bit is “0”.
The bits shown as “0” should be written “0” and the bits shown as “1” should be written “1”.
